This guide will walk you through the process of correcting the homing position of the front windscreen wipers on your E46. If your wipers are misaligned or not functioning properly, follow these steps carefully to adjust and fix the issue.
Step 1: Gather Tools and Materials:
Ensure you have the necessary tools and materials ready:
- Wrench or socket set
- Torx or allan key set
- Flathead screwdriver
- Protective gloves
- Lubricating oil
- Park your car in a safe and well-lit area.
- Pop the hood and securely prop it open.
- Locate the plastic caps near the bonnet that conceal the wiper arm nuts.
- Gently remove these caps to access the wiper arm nuts.
- Using the 15 mm wrench or socket set, carefully loosen and remove the single nut securing each wiper arm.
- Lift the wiper arms off the windscreen.
- Remove the plastic housing beneath the wiper arms. (so you can clean and lube the parts)
- Locate the cabin filter housing under the hood, remove it by using torx T30 bit to access the joint mechanism.
- Install the wiper arms on the windscreen. (slightly tighten them so you can move the wiper motor by hand)
- Identify the 10 mm nut on the joint mechanism. (shown in the picture)
- Gently loosen the nut by no more than 4 turns; make sure it's not completely removed.
- Using the flathead screwdriver hold the golden tab below the 10 mm nut.
- For the initial adjustment while holding the golden plate with a flathead screwdriver, reposition the wipers about 20 cm or 7-8 inches from the bottom of the windscreen to prevent damage to the car. (Ensure that the gold-colored plate doesn't move while you reposition the wipers)
- Tighten the wiper arm nuts and the 10 mm nut securely.
- Sit in the driver's seat and turn on the wipers to observe their movement.
- Exit the car and, if necessary, slightly loosen the wiper joint 10 mm nut.
- With your hands, adjust the wiper position as needed (closer or further from the windscreen bottom) to achieve the desired homing position.
- Tighten the 10 mm nut and repeat this adjustment process as needed, testing the wipers each time.
- Once the desired homing position is achieved lubricate all moving components of the windscreen wipers under the hood to prevent seizing in the future.
- Reassemble all of the removed components.
- Ensure all nuts and bolts are securely tightened!
- If the wipers are not moving or stuck, check the Nr49 5 A and Nr59 30 A fuses for potential issues.
- If the problem persists, there may be an issue with the windscreen wiper motor that requires further inspection or replacement.
